The pin’s “smart” pull-up shuts off while the pin is forced low. This is done to reduce the standby and shut-
down current.
The DFN and QFN packages have a contact on the bottom of the package. This contact is conductively
connected to the die substrate, and therefore should be unconnected or connected to the same ground as
the device’s V
